l MACHINE FOR SHREDDING SUGAR-CANE.

SPECIFICATION forming part of Letters Patent No. 247,874, dated October 4, 1881. Application tiled July 6, 1881. (No model.)

To all whom it may concern Be it knownthat I, GEORGE A. BAZE, of Havana, Cuba, have invented a new and Improved Machine for Shredding Sugar-Gane,.of which the following is a full, clear, andrexact description.

The object of this invention is to more thoroughly tear apart and separate the fibers of cane preparatory to extracting the juices and sugar therefrom.

The invention consists of a horizontal drum having series of knives fixed radially upon it, and provided with blunt edges, revolving within a cylinder, in the top of which is a longitudinal openingforthe introduction ot'the cane, and in the sides and bottom of which are series ot' radially-adjustable blades, between which the knives on the drum move when the machine is in operation, whereby the cane is torn and shredded to the condition best adapted for the extraction ot' its juices. 'E

In the accompanying drawings, Figure 1 is a plan of the device partly in section, and with.

parts broken away to exhibit other parts. Fig. 2 is a vertical section of the same on line x x, Fig. 1.

Similar letters of vreference indicate correspending parts.

In the drawings, A represents the frame of the device, supporting the cylinder B, which latter is surmounted by a hopper, C, extending its entire length over an opening,B, made in the top of said cylinder B, and in the bottom of said hopper G are secured transverse parallel bars, forming a grating, N, which is xed at an angle orslope shown, so that the knives b b, as they revolve, shall pass between said gratingbars and easily hook over and break down the cane that is fed athwart said grating N. Along the sides and bottom ot'said cylinder B are secured, in this instance three, boxes, D D D, though their number may be increased or diminished, that open Ainto said cylinder B, and contain blocks E, extending theirwhole length, and carryingblades a, pointing inward to a common center-the d rum G. Said blocks E are adjustable to and from the said drum G by means of the screws F, that are passed through the centers of the boxesD D through screw-threaded holes g, and have their enlarged ends entered into sockets h in the centers of said blocks E, and revolubly held therein by plates 7c, ixed over said sockets h, and said blocks E are steadied in their movements vby cross bars or braces O,f1xed on the heads ofthe screws F, at right angles there-A to, and having guide-pins O projecting inward from their ends, parallel with screw F, and entering corresponding guide-sleeves, D', which project outward from said boxes D. The said screws F are turned, and the blockslh` thereby adjusted in and out, by means of the screw cross-handles F.

The drum G is fixed longitudinally in the cylinder B-on a shaft, G', that is journaled in the ends of said cylinder B. Secured on the drum Gr are series of dat knife-plates, S, each having three curved knives or teeth, b, forming part ot' the plate, arranged side by side on the said drum G in such a manner that the said knives b b form three separate spirals about said drum G and extendhetwcen or interlnesh with the knives a a ot' the blocks E, and up between the bars of the gratingN. The knives have square or blunt edges and tear or shred, but do not cut, while the grating prevents the cane from crowding into the machine and clogging the knives. It will thus be perceived that the gratingNoperates to rcgulatethe feed. Discharge-pipes M, through which the shred ded cane is ejected from the cylinder B, are located in convenient positions on sides and ends of said cylinder B, as indicated in the drawings. i

The shaft Gis extended outward atone end, and carries on it a cog-wheel, H, into which gears a corresponding wheel, I,on the drivingshaft K, which shaft K is moved by the pulley L; or the device may be operated by power applied in any other convenient manner.

It is not designed that the blades a a. shall be sharp, it being the purpose to shred or pull apart the bers ot' the cane rather than to cut them. The drum Gr being put in revolution,

. the cane is fed into the hopperC lengthwise on the gratingN, and the knives b b, reaching up between the bars of said grating N, engage over the cane and break it down through said grating N into the cylinder B, where the cane is then subjected to the action of the knives and IOO a cylinder containing fixed adjustable blades, a revolving drum provided with curved blades, and a hopper containing an inclined grating, through which the revolving' blades projecl, as described.

2. In a cane-shredding,` machine, the combition, with the revolving curved knives b b, of 2o the inclined grating N, as and for the purpose specified.
